Methods, systems, and techniques for application isolation by remote-enabling applications are provided. Example embodiments provide an Adaptive Rendering Application Isolation System (“ARAIS”), which transparently and dynamically enables applications to run in an isolated execution environment yet be rendered locally via a local isolator application having one or more cohesive application-isolation interfaces in a manner that facilitates providing the ARAIS indications of user actions that are otherwise lost and executing functions that are otherwise unavailable during fully secure isolation sessions absent one or more cohesive application-isolation interfaces. In one embodiment, the ARAIS includes an orchestrator server which comprises remoting level determination logic and rules engine, pre-computed graphics libraries, connection support logic, data repositories for objects such as a render cache, whitelists, blacklists, client privileges, and application information, and one or more secure containers running remote application instances. These components cooperate with the one or more cohesive application-isolation interfaces of the isolation application to provide isolation sessions with a user experience that is typically available only during non-isolation sessions.
